Why require doesnt work

Ruby JRuby
1

I have JRuby 1.8.6 that work on windows xp and my IDE is netbeans 6.7.
require’s method doesnt work when I want work with Win32API or Qt.

the code is:

require “Win32API”

message = “This is a sample Windows message box generated using
Win32API”
title = “Win32API from Ruby”

api = Win32API.new(‘user32’,‘MessageBox’,[‘L’, ‘P’, ‘P’, ‘L’],‘I’)
api.call(0,message,title,0)

my problem is when I just type require ‘Win32API’ its not work and give
me an error:
`require’: no such file to load – Win32API (LoadError)

Should I do special work?like copy file or else?I have same problem with
Qt!

Hi Midose ,

How do you launch your JRuby? Oh, and there is no such JRuby version
as 1.8.6. Can you show the output from jruby -v?

I just tried your example in the latest JRuby and it worked just fine
for me here.

Thanks,
–Vladimir

Im sorry, you say true it’s JRuby 1.2.0

How do you launch your JRuby?
I use JRuby in Netbeans 6.7(IDE).

sorry if I can’t speak very good and thanks for your help,

Hi Midose,

first, you should try to update your JRuby Environment to JRuby 1.3.1
(or 1.4.0RC3 if you like).
Then please try again.

Cheers
Michael

JRuby 1.2 didn’t support Win32API, so you’d need a more recent
version. Actually, it seems that even JRuby 1.3.1 didn’t support
Win32API, but it should work in JRuby 1.4.0RC3 (and in the upcoming
1.4.0 release).

I don’t know this, sorry.

thanks for your help,
